FLASH-LIGHT.

Specification of Letters Patent.

Application filed December 30, 1914.

To all l/wfm iti/my (einem:

lle it known that l, BERNARD Biixiinie'i'.

va `citizen of the United States, and a resident of-lronx, in the county of Bronx and State of New York. have invented certain -new and useful Improvements in Flash- Lights. of whieh the following is a speeii'i cation.

rllie invention pertains more partieularllif to flash lights adapted to be carried iii the upper vest pocket without inconvenience and in the saine manner that a fountain pen fearried.

i rlfhe lasli light of my invention isprovided with a spring clip or ineinber adapted, when the flash light is plaeed in the upper vest.

r"-poeket. to embrace between itself and the 4 ,side of the easing of the artiele. the thickness Vof the flash light to resemble in appearanee'a fountain pen. and upon the exterior kof this outer shell or easing l secure a of the material of the vest at the outer side of said pocket, the flash light being thereby 'helld Isecurely.

rPhe present invention resides more particularly iii the structure of the easing and in the eleetrie circuit features. ln the. present instaure a manually operative contag't is rigid with the exterior easing and has a portion to be pressed inwardly through said easing for engaging a eoiiduetor connected with Vthe battery. thereby to eoinplete the eireuit. and this eondiietoiis preferably in the forni of a sleeve elosely fitting within ybut Ainsulated from the exterior easing and in y.eleetriealA engagement with a spring. which engages one end of the battery and is insulated froin the exterior casing. The easing of niy invention iscoinposed of two inain parts secured together by bayonet y joints.

V,ln f ai'rying out my invention Vl preferably construct the barrel or exterior easing spring elip` preferably imitating as far as .possible the spring elip on the side of the barrel of a fountain pen. and lv preferably lutilize this spring clip as the niaiiually opr erative ineans for closing the circuit when it isdesired that the lamp shall light.. l do not limit my invention however to the use of the spring clip as a circuit. closer` Patented May 1G, 1916.

Serial No. 879,632.

since it is obvious that other forms of circuit elosers may be used either in .conneo tion with or separate from the spring clip.

llie invention will be fully understood froin the detailed description hereinafter presented. reference being had to the accompanying drawings, in which:

Fig'. 2is a ventral vertical section on an enlarged scale through the same.. taken on the dotted line Zeil of Fig. 1; Fig. 3 is a detached perspective view of an inner non-Conducting lining for the interior of the handle end of the flash light, said lining having a sniall aperture in one side thereof for the passage of the eireuit eloserflfig. l is a detached perspective view of a metal sleeve which in use lits within the lining shown in Fig. 3 when said lining is within the exterior shellor easing of the flash light; Fig. 5 is a sectional view through the nietal portion of the flash light taken at: right angles to the section of Fig. 2 and is presented to illustrate the. bayonet loelts for connecting the two n'iain sei-tions ol the exterior casing together: liig. (l is a detached side elevation of the inner end portion of the outer section of the iiiain casing; Fig. i' is a top view of the saine. and Fig. S is a horizontal section through the flash light 'taken' on the dotted line Sf8 of Fig. '2. i

ln the drawings. 10 designates the exterior shell or asing of the flash light, and

this shell or 'asing isof elongated forni'and meant to imitate as far as convenient the appearance of a fountain pen. The casing 10 will preferably be of metal and at one, end carries a lainp 11 and reflector l2 therefor. The easing 10 is shown as made in two sections 13. l-l connected together at their meeting portions bybayonet joints. The seetion 13 near its inner end flares outwardly. as at and at the outer edge of this flaring portion 15 said easing section is formed with an inwardlyy set straight portion 16. this construction creating an annular shoulder 17 at the. adjoining edges of said portions l5. lo. as clearly illustrated in Figs. 5. (5 and T. The portion 16 of the Casing section lf3 is in the nature of a band and e 18 for the bayonet locks, these grooves having at'the inner ends of their transverse portions outwardly projecting recesses 19 which serve to aid in locking the two sections of the main casing against accidental rotation one upon' the other, tending to separate them. The casing section 14 is plain and cylindrical from end to end and snugly receives Within itsv inner end the band 1G of the casing section 13,*the edge of the inner end of the section 14 abutting against the shoulder 17 of the casing section 13, this construction and arrangement affording a firm connection between the two casing sections and creating a neat joint at their meeting portions. The inner end of the casing section 14 is indented, as at 20, to form two small studs opposite to each other to enter the opposite grooves 18 of the bayonet locks.

In assembling the casing sections 13, 14, the band 16 of the section 13 is inserted within the inner end of the section 14 in position for the studs at 20 to enter the open ends of the grooves 18 and thereupon said band 1G having been fully inserted within the casing section 14, the section 13 is given a rotary movement to carry the horizontal portions of the grooves 18 along the studs- 20,said studs upon reaching the inner ends of the said horizontal portions of Vthe grooves 18 getting into line with the recesses 19, and thereupon under the pressure of the conducting spring 21, the sections 13,` 14 are moved very slightly in a direction trom each other and the said studs enter the recesses 19 to a sullicient extent to lock the sections 13, 14 against accidental rotation one upon the other. The outer end of the casing section 13 is formed at 22 with bayonet lock grooves, and the opposite sides of the re- Hector shell,12.are indented, at 23, to form studs to engage said grooves, the grooves 22 and studs 23 corresponding exactly with the grooves 18 and studs 2.0 provided at the adjoining ends of the casing sections 13, 14, and therefore not requiring further specific description, the dotted lines at`l the lower portion of Fig. 2 sufliciently illustrating the grooves 22 and studs 23. The reflector 12 is therefore held within the outer end of the casing section 13 by bayonet locks, and said reflector at its outer edge is formed with a shoulder 24 to engage the outer edge of the casing section 13. The reflector 12 has a threaded neck 25 to receive the socket 2,6 of the lamp in a customary manner.l The lamp 11 is of usual character and has one terminal 27 in engagement, as usual, with one pole ofthe battery 28.. The battery 28 will customarily be formed of two cells in end to end relation and covered around their sides by paper or other non-conducting ma the sleeve 30.

.against by the coiled spring 21 which is a conductor and has one or more of' its coils in electrical engagement with the sleeve 30. The sleeve 30 is insulated from the uietal casing section 14 by means of the sleeve 2f) and also by means of a disk of paper'or the like 31 fitted within the closed end of the section 14. lVithin the outer end of' the sleeve 30 is placed a Second disk, which I number 32, ofv paper or the like, the disk 32 being in face to face contact with the disk 31 and receiving the outer end of' the springr The sleeves 29, 30 are in` the form of elongated split tubes and therefore may be readily applied to position with the outer or handle portion of the easing or easing- -section 14. The disk 31 binds tightly withthe outer end of the battery 28 will be from the battery to the spring 21 and thence to 'l`l1e sleeve 2f) is formed near its forward end with an aperture or hole 33, and this aperture 33 is in linewith a corresponding aperture 34 formed in the casing section 14 and exposes at said aperture 34 a small portion of the conducting sleeve 30. The electrical connection of the outer easing of the flash light with the sleeve 30 to complete the circuit ismade at the openings 33, 34, and in the present instance I utilizev a spring clip as the circuit closer, said clip being secured by rivets to the caslng section -14 orotherwise suitably connected with said casing so as to be in electrical-eirv gagement or connection therewith. 0n the outer end/of the spring clip 35 is a ball or enlargement 36 adapted by the pressure of the thumbapplied thereon to be moved, on'

'the flexing of the' spring 35, inwardly through the openings 34, 33, against the from the batteryv to the spring 21 and through the sleeve 30 to the spring clip or v sleeve 30, thereby to complete the circuit' conductor for completing the circuit, said liningl being tubular and fitting the inner walls of the rear casing section and having au opening in its side registering with the a forcsaid opening in the side of said casing, and said conductor being a sleeve fitting within said lining.
